DUMPING CAR.

Application filed January 19, 1924. Serial No. 537,341,

To all whom it may concern:

Be it known that I, MELVIN A. CArIDLE', .a citizen of the United States,residing at Vanwood, in the county of Raleigh and State of WestVirginia, have invented certain new and useful Improvements in,

Dumping Cars, of which the following is a specification, referencebeinghad to the accompanying drawings. I

This invention relates to certain improvements in dumping cars and hasrelation more particularly to a device of this character especiallydesigned and adapted for use in connection with mining and it is anobject of the invention to provide a novel and improved car of thischaracter of sufficient strength to permit thesame to be directly loadedby a shot or blast together with means whereby the load of the car maybe readily and conveniently discharged therefrom. p

Another object of the invention is to provide a novel and improveddevice of this general character especially designed and adapted for usein connection with carrying out of slate from amine and wherein the caris constructed in a manner whereby the loadthereon may be readily andconveniently discharged at either side of the car.

It is also an object of the invention to provide in connection with acar of this kind novel and improved means to prevent shooting of theslate during a loading oper-- ation, surface kinking or spreading therailsof the trackway upon which the car travels.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved dumpingcar whereby certain important advantages are attained and the devicerendered simpler, less expensive and otherwise more convenient andadvantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to described the same with refrence to the accompanyingdrawings, wherein I Figure 1 is a view in side elevation illustrating acar constructed in accordancewith an embodiment of my invention; I

Figure 3 is a view in end elevation of my improvedcar as hereindisclosed, a second position of certain ofthe parts being indi cated bydotted lines, such position being taken when thebody is in dumpedposition;

Figure t is a transverse sectional view" taken centrally of the car asillustratedin Figure 1; V I Figure 5 is a detail view partly inelevation and partly in section illustrating the means herein employedfor use in connection with the car to prevent surface kinlo ing orspreadingfof the rails;

Figure 6 is a view in section taken through Figure 5, showing a sectionthrough the rail and ramp.

As disclosed in the accompanying drawings, A denotes the front and reartrucks of a car, said trucks travelling upon a track-i way 13. Thetrucks A are connected by the longitudinally disposed sills 1 arrangedat opposite sides of the trucks A and which have their forward endportions connected by the transversely disposed and underhung endsills2, said sills 2 extending a predetermined distance beyond opposite sidesof the trucks A. 1 Operatively engaged with the central portions of theend sills 2 and with the trucks A is'a draft bar 3.

Mounted upon each of the trucks A is an upstanding ,bolster or plate 4therein dis closed as in the form of an inverted V. The apex portions ofthe bolsters or plates 4- con; stitute bearings for the pivot or fulcrummember 5 comprised in the tilting body or bottom of the car. Theportions 6 of the member 5 directly engaged with the bolsters ted tohave rocking movement in either di rection'whereby the dumping body .orbottom of the car may be titled toward either side of the car structure.

The car body or bottom comprises the transverselydisposed;slats 9hav'ing their central portions suitably connected'to the member 5and'then' outer end portionssecured to the longitudinally disposed beams10.. The upper portions of the bolsters or plates 1 at opposite sidesare connected by the brace beams or members 11 whereby the strength ofthe car in its entirety is materially increased.

Associated with each side of the car is a laterally swinging frame F,said frame as herein disclosed comprising a plurality of longitudinallyspaced posts 12 having their lower or inner end portions p'ivotallyconnected, as at 14, with. similar end portions of the end sills 2 andan intermediate or central sill 15. The upper or outer end portions ofthe posts 12 have secured theretoa beam 16 and the posts 12 are of suchlength that when the same are in substantially a vertical position thebeam 16 will have close contact with the inner face of a beam wherebythe dumping body or bottom of. the car is supported in substantially ahorizontal position and against til-ting. or

dumping movement at such side of the car I structure. The frame F isnormally maintained raised through the medium of the against inwardswinging movement by the latches 18 pivotally engaged with the endportions of the sills 1 and engageable with a pin or keeper 19 carriedby the end post 12.

The upper portions of the bolsters or plates 4 have interposedtherebetween and supported thereby a longitudinally disposed beam20positioned above and in parallelism with the draft bar 3. Supported bythe bar and the beam 20' is a vertically disposed shank or pin 21 uponwhich are rotatably mounted the connected pulleys 22 and 23-. The upperpulley 22 being of less radius than the lower pulley 23. The lowerpulley 23 constitutes the power pulley and has operativ'ely engagedtherewith a flexible cable fulcrum member. 5 is provided with the out-24 which is of alength to extend beyond an end of the car and terminatesin a loop or eye 25 with which the motor or traction means is adapted tobe coupled in order to impose a requisite pull tocause the desiredrotation of the pulleys 23 and 22.

The upper pulley 22 has operatively engaged therewith the flexiblemember 26 the outer endof which being adapted to be selectively engagedwith an inwardly disposed hook member 27 carried by each of the frames Fin accordance with'the direction toward which it is desired that thedumping car body or bottom tilts.

The opposite end portions of the pivot or standing and horizontallydisposed arms 28,said arms being of such a length and position as tointersect and be under the path of travel of a frame F as thesame isswung inwardly and downwardly whereby the dumping body or bottom iscaused to tilt at the side of the car to which the inwardly swingingframe F is operatively engaged. By changing the connection of theflexible cable 26 with either of the hook means the car is loadedwithout requiring the loosened material to be manually handled. Afterthe car has received a shot the same is transported to the place ofdumping.

In, order to prevent surface kinking or spreading of the rails of thetrackway at the time of a shot I find it of advantage to provideadjacent each of the rails and between the same a supplemental track orramp 29 having its upper surface extending above the upper surface ofthe rails and its end. portions suitably rounded so that the trucks mayride upwardly upon such supplemental track or ramp. With the car mounteddirectly upon the supplemental track or ramp at the time of a shot, itwill be understood that no injury will be imposed upon the rails of thetrackway. In order to permit the desired use of the rails or ramp 29each of the wheelsfof a truck has its tread of pronounced width, asillus trated in Figure 6 of the accompanying drawings, with the railflange 30' positioned in substantially the longitudinal center of suchtread surface.

From the foregoing description it is thought to be obvious that adumping car constructed in accordance with my inven-' tion isparticularly well adapted for use by reason of the convenience andfacility with which it may be assembled and operated, and it will alsobeobvious that my inven tion is susceptible of some change andmodification without. departing from the principles and spirit thereofand for this reason- I do" not wish to be understood as limiting myselfto the precise arrangement and formationof the several parts hereinshown in carrying out my invention in practice except as hereinafterclaimed.

I claim 1. In combinationwith a car body,- a tilting body mountedthereon, a swinging frame mounted upon the body and serving to hold thetilting body against movement, means for swinging the frame in onedirection, an'dmeans carried by the tilting body engageable with saidframe when moved in one direction to impart tilting movement to thetilting body.

2. In combination with a car body, a tilt ing body mounted thereon, aswinging frame mounted upon the body and serving to hold the tiltingbody against movement, means for swinging the frame in one direction,means carried by the tilting body engageable with said frame when movedin one direction to impart tilting movement to the tilting body, andmeans for normally main taining the frame in a position to hold thetilting body against movement.

3. In. combination with a car structure, a dumping body mounted thereonfor swinging movement in opposite directions, .sep-

arate means for holding the body against.

tilting movement in opposite directions, means selectively inoperativeposition to permit the body to tilt in one direction.

4. In combination with a car structure, a dumping body mounted thereonfor swingengageable with said holding means for adjusting the sameintoing movement in opposite directions, separate means for holding thebody against tilting movement in opposite directions, means selectivelyengageable with said holding means for adjusting the same intoinoperative position to permit the body to tilt in one direction, andmeans carried by the dumping body engageable by either of the holdingmeans when moved into inoperative position to impart tilting movement tothe body.

5. In combination with a car structure, a shaft rotatably supportedthereby, a dump iug body movable with the shaft, frames supported by thestructure and arranged at either side of the shaft for holding the bodyagainst tilting movement, means for moving either of the frames intoinoperativeposition to permit tilting movement of the dumping body, andoutstanding arms carried by the shaft with which a frame engages whenmoved into inoperative position to impart tilting movement to the body.

In testimony whereof I hereunto aflix my signature.

MELVIN A. CAUDLE.
